Patricia, thank you so much for you answers. I have two more questions.

1. During the two years of my non lucrativo visa that I will be using for residency, must I be present in Spain itself for 183 days of each calendar year, or 183 days in the larger Schengen area?

2. If I apply for Spanish citizenship after these two years, what are the residency requirements during the year or so that I must wait for citizenship?

Thanks in advance for any help you can give. I searched the entire thread and could not find answers to these questions.
